By its very definition, comparing the retro roadster class by performance figures is a bit silly. These bikes aren't created to go fast, they're created to recapture some sort of fundamental two-wheeled experience with handsome looks, easy-going power and a nebulous thing called "character." That's why we prefer the Triumph Scrambler to its slightly faster sibling, the Bonneville: character. Still...

In fact, this whole class is a little hard to define compared to, say, 600cc sportsbikes. Retro bikes like these don't share common capacities, engine configurations or much at all beyond old technology re-interpreted with modern manufacturing. So, we've chosen all air-cooled bikes that aren't overtly specialized in either riding position or purpose and only bikes that are available in the USA. We've also thrown the Suzuki TU250 and a 1969 Honda CB750 into the mix just to give things a bit of perspective. Is the BMW R1200R really a direct rival for the Moto Guzzi V7? Probably not, so we're not picking winners, allowing you to draw your own conclusions. Don't see a bike you feel should be included? Look up the numbers and drop them in comments.

People purchasing retro roadsters tend to do so based on brand loyalty, image and whichever ratio of chrome to paint fits their particular taste. Our two favorite bikes here, the Moto Guzzi V7 Classic and the Triumph Scrambler are also two of the slowest, running counter to our usual preference for performance. One thing these numbers indicate about the CB1100 is that it should be a great highway cruiser, with a superior torque to weight figure over the above two bikes and a smooth inline-four to boot. While the Honda is cheaper than the Moto Guzzi Griso 1100, it looks like it'll retail for about the same as the Harley XR1200, all three of which look very closely matched. Looking for style and speed? The Ducati GT1000 or the R1200R are your best bets. And yes, the TU250 does feel as slow as its numbers suggest.
